Can we call it deflationary tokens, it's a token which you hold to receive some rewards by either with their native currency or with a stable coin such as; usdt, busd, dia or any other stable coins.
Such token can't be trusted reason because, there's always high market dump, and lack of development and the rest since all people focused on the rewarding and earnings at weekly or monthly. These rewards are subjected to the amount of sell and buy or any transaction executed, so if none was done either no much trades this simply your chances of earnings are very slim.
